There isn't one. I mean back to kernel's way. Why should U-boot use different way from kernel to allocate resources since most PCI parts are similar (equivalent) to kernel?
This is not a change "back" then, as we never used this setup before.
Yes, I know. Hopefully not too much. This change will only change the

*ALL* of these need thorough regression testing after such a significant change.

All right. I will do it in my branch and not to submit patch for this.

What exactly is the problem you're trying to fix? The fact that it's different is IMHO not enough of a reason to change it.
The problem is some bridges have 64K limitation on I/O space, which requires special care in allocation. I am fixing it in the kernel.
